Definitions

  • This invention relates to an Li-based hydrogen storage composition and a method of providing a source of hydrogen.
  • the melting temperature of LiH is 680° C., and it decomposes only at temperatures above 720° C. This feature alone excludes LiH from any practical applications because not only does the hydride melt before decomposition, but also the decomposition temperature is far too high for any reversible hydrogen storage application.
  • LiAlH 4 is the most significant.
  • This complex hydride is a common reduction agent and is used in many reactions, for example in the production of borates or silanes, according to the following reactions:
  • LiAlH 4 is not usable for reversible hydrogen storage because it cannot be re-hydrogenated under gaseous hydrogen. After decomposition, LiAlH 4 can be re-synthesized only in the course of a chemical reaction, for example:
  • LiAlH 4 is not practical for reversible hydrogen storage.
  • Li-based hydrides which also are not usable for reversible, gaseous hydrogenation and to date, there are no reports of any Li-based metal hydrides capable of hydrogenation/dehydrogenation cycling under practical hydrogen pressures.
  • This invention deals with a new generation of Li-based metal hydrides with totally new hydrogenation properties. These hydrides undergo hydrogenation/dehydrogenation cycling under practical conditions of hydrogen pressure and temperature and are thus suitable materials for hydrogen storage.
  • Li is the basic metallic element which forms complex hydride compositions with other elements.
  • the presence of these other elements causes changes in hydrogen sorption properties of the Li-based hydride, so that the hydride becomes usable for reversible hydrogen storage.
  • a hydrogen storage composition having a hydrogenated state from which hydrogen is liberated and a dehydrogenated state which absorbs gaseous hydrogen to produce said hydrogenated state, wherein said hydrogenated state comprises:
  • said hydrided composition liberating hydrogen to form a dehydrogenated state comprising a compound of lithium and said at least one element E, or a solid solution of lithium and said at least one element E;
  • a method of producing a source of hydrogen gas comprising liberating hydrogen from a composition of the invention, at an elevated temperature, with formation of the dehydrogenated state of said composition, removing the liberated hydrogen, and regenerating said hydrogenated state by exposing said dehydrogenated state to hydrogen gas.
  • a method of producing a hydrogen storage composition of the invention comprising ball milling at least one lithium component selected from elemental lithium and lithium hydride with a component selected from i) at least one metal M, as defined hereinbefore, a hydride thereof, or a mixture thereof; ii) at least one element E, as defined hereinbefore; and iii) at least one of a metal M, as defined hereinbefore, and a hydride thereof; and at least one element E, as defined hereinbefore, to form a lithium-based composition, and, when necessary or desired, hydrogenating the lithium-based composition.
  • FIG. 1 illustrates graphically thermodynamic properties of Li—Be—H hydrides of the invention in the form of a Van't Hoff plot
  • FIG. 2 is an X-ray diffraction pattern of Li 5 Be 3 H 11 a hydride of the invention after formation by hydrogenation;
  • FIG. 3 is an X-ray diffraction pattern of the hydride of FIG. 2 after dehydrogenation to liberate hydrogen;
  • FIG. 4 illustrates graphically the regeneration of Li 5 Be 3 H 11 from the dehydrogenated state by absorption of hydrogen at 270° C. and 300° C.;
  • FIG. 5 is a pressure-composition isotherm for hydrogen desorption of Li 5 Be 3 H 11 at 300° C.
  • FIG. 6 illustrates graphically, hydrogen desorption for a hydride material derived from LiH and C.
  • dehydrogenated state refers to a state produced by liberating hydrogen from the hydrogen storage composition of the invention in the hydrogenated state; it is not intended to indicate complete removal of hydrogen from the composition, and indeed the invention contemplates both complete removal of hydrogen and partial removal of hydrogen from the hydrogenated state of the composition.
  • Li-based hydrides in which the at least one element E forms a compound or solid solution with lithium, after decomposition of the hydride.
  • Li-based hydrides which contain at least one metal M and at least one element E so that the above characteristics in 1 and 2 are present.
  • Hydrided compositions in this group contain two or more metallic components, of which one is lithium.
  • the second metal or metals, M is chosen from elements that are able to form compounds with hydrogen, such as Be, Mg, Ti, V, Zr, which form the following respective hydrides: BeH 2 , MgH 2 , TiH 2 , VH 2 and ZrH 2 . None of these metals M forms an intermetallic compound or solid-state solution with lithium, as reflected by their respective phase equilibrium diagrams.
  • the hydrided composition according to the invention is a complex hydride of lithium and the at least one metal M.
  • the hydride formula can be written as follows:
  • x is an integer of 1-5
  • y is an integer of 1-3
  • M may comprise one or more different metals M.
  • the above complex Li-based hydrides differ from the respective hydrides of their components, LiH and MH 2 , in both crystallographic structure and thermodynamic properties. Specifically, the changed equilibrium pressure of hydride formation allows the system to be used for reversible hydrogenation cycling.
  • the metal M is beryllium.
  • Normally beryllium hydride, BeH 2 is extremely difficult to fabricate. So far it has been possible to produce it only by complicated organometallic methods. Until now there was no reported synthesis of BeH 2 from elements, i.e. from beryllium and hydrogen, and also in no case was beryllium hydride found to be capable of reversible hydrogenation performance.
  • the respective components are intermixed and then ball milled.
  • the components can be used either in the form of metals, e.g. Li and M or in the form of the respective hydrides, e.g. LiH and MH 2 . Mixtures of the metals and hydrides can also be used.
  • ball milling is applied for proper intermixing of the components with as fine microstructure as possible.
  • Such ball milled material is very active and can be easily hydrogenated to form complex hydrides.
  • at least part of the hydrogenation reaction may be carried out during ball milling and finished during the first dehydrogenation/dehydrogenation cycle.
  • the ball milling achieves a fine particle size compound of particles having a size below 10 microns, preferably below 100 nanometers and more preferably below 10 nanometers.
  • the process may employ elemental lithium or lithium hydride, and may employ elemental metal M, the hydride thereof, or a mixture thereof. If at least one of the components is employed as the hydride in the ball milling the resulting lithium-based composition functions as a hydrogen storage composition but additional hydrogen may be absorbed by hydrogenation to increase the supply of hydrogen available in the composition. If only elemental components are employed hydrogenation is necessary, during or after the ball milling, or hydrogenation may be carried out both during and after the ball milling.
  • the progress of formation of the complex hydride or hydride precursor can in many cases be observed by determining physical characteristics periodically during the ball milling, for example, X-ray diffraction patterns, which show characteristics of the new complex, rather than the known characteristics of the individual starting components.
  • hydrogen liberation is achieved by heating the hydrided composition at a temperature of 100° C. to 300° C., depending on the hydrogen pressure, and the hydrided composition is regenerated from the dehydrogenated state by heating at a temperature of 100° C. to 350° C. under a gaseous hydrogen atmosphere at a pressure of 5 to 60 atm.
  • Li-based hydrided compositions from this family differ from the complex hydrides of Group 1 mainly in the mechanism of the hydrogenation reaction.
  • lithium hydride is present in the hydrogenated state, in the form of either a complex hydride or simply LiH, but it decomposes upon dehydrogenation.
  • Properties of lithium hydride, especially the decomposition temperature are changed by the presence of other elements E, which may react with lithium in the desorbed state, or form solid solutions with lithium.
  • hydrogen can be released from lithium hydride at temperatures between 100 and 350° C., preferably 150° C. to 300° C., instead of about 720° C.
  • lithium or lithium hydride is the main component and the stability of LiH is reduced as a result of the presence of one or more of the following elements E:
  • metals Zn, Mn, Ni, Fe, Cr, Cu, Al, Ca, Na or K.
  • the amount of the element E depends on the particular system and specifically on phases that can be formed with lithium, stable or metastable. In general, a molar ratio of Li to the at least one element E is between 7:1 and 1:2.
  • the metalloids are very effective in changing the properties of LiH, as particularly demonstrated by carbon and boron.
  • Li—C equilibrium phase diagram shows only one stable phase, Li 2 C 2
  • the present invention demonstrates that destabilization of LiH occurs within a wide range of compositions.
  • Li—C—H hydrides are able to desorb a certain amount of hydrogen at much lower temperatures than LiH, i.e. between 150 and 230° C., and can be at least partially re-hydrogenated for example at 200° C.
  • Boron also changes stability of LiH in such a way that hydrogen desorption can occur at temperatures between 300 and 350° C. Re-hydrogenation of these hydrides can be performed at similar temperatures.
  • Li—Zn—H hydrides can desorb hydrogen at temperatures ranging from 200 to 250° C.
  • Li-based hydrides were fabricated by mechanical alloying. Li or LiH was the main component of the alloy, which was ball milled with the at least one element E. As a result of this process followed by a dehydriding/dehydriding cycle, an alloy with new properties was obtained.
  • the ball milling achieves a fine particle size compound of particles having a size below 10 microns, preferably below 100 nanometers and more preferably below 10 nanometers.
  • the ball milling may be carried out with lithium, lithium hydride, or a mixture thereof, and the resulting lithium-based composition hydrogenated to produce the desired level of hydride.
  • the progress of the ball milling may be monitored by determining physical parameters of the lithium-based composition, such as X-ray diffraction patterns of a solid solution of lithium and the element E, or a compound of lithium and the element E, characteristic of the dehydrogenated state, or other physical parameters characteristic of the hydrogenated state, depending on wither lithium or lithium hydride is employed in the ball milling.
  • Li—V—H hydrides are the most characteristic examples of this group of Li-based hydrides. Two kinds of behavior can be observed for these hydrides, namely: reversible hydrogenation based on the formation of altered V-based hydrides as a result of the presence of Li or LiH, and destabilization of LiH as a consequence of the interference by vanadium or vanadium hydride. As a result, new and improved hydrogenation characteristics are observed in the Li—V—H hydrides.
  • Li-based hydrides with elements from both group 1 and 2 also belong to this family of complex hydrides.
  • the ball milling achieves a fine particle size compound of particles having a size below 10 microns, preferably below 100 nanometers and more preferably below 10 nanometers.
  • new Li-based hydrides from the above three groups exhibit a variety of new properties, which are not limited to reversible hydrogen storage. They represent new materials with unique and unexpected properties. They find many possible applications, such as chemical agents or materials for electrochemistry, i.e. for rechargeable metal hydride batteries.
  • different complex, special structures such as the layered structure of Li 5 Be 3 H 11 or similar hydrides were found to have unique properties, for example electrical conductivity, magnetic properties and heat transport, which can be useful in various applications.
  • Hydrogen absorption into the dehydrogenated state of the hydrogen storage composition of the invention is typically carried out at a temperature of 100 to 350° C. under a hydrogen pressure of 5 to 60 atm. Hydrogen is typically liberated from the composition in the hydrogenated state by heating to a temperature of 100 to 300° C.
  • Li 5 Be 3 H 11 hydride was fabricated in the following way.
  • Li 5 Be 3 H 11 was subjected to hydriding/dehydriding cycling in a gas titration system. Although the cycling can be performed at various temperatures according to the Van't Hoff plot shown in FIG. 1, the rate of the reaction is faster at higher temperatures.
  • FIG. 4 shows absorption of hydrogen in the regeneration of Li 5 Be 3 H 11 at temperatures of 270° C. and 300° C.
  • the pressure composition isotherm for desorption at 300° C. is presented in FIG. 5 .
  • the respective amounts of lithium hydride and carbon, boron, silicon, zinc, iron or vanadium were sealed in steel vials under argon atmosphere inside a glove-box.
  • the molar ratios between LiH and the other elements were, in each case, 1:1.
  • Ball milling was performed in a high-energy ball mill SPEX 8000. The milling was performed by using steel balls, for a period of time of two hours. Hydrogenation properties of these hydrides were measured in the gas titration system. Normally, LiH does not exhibit any hydrogen desorption over the studied temperature range up to 350° C. However, for all of the studied compositions consisting of LiH+other element, a significant desorption of hydrogen occurred at much lower temperatures.
  • FIG. 6 shows hydrogen desorption which was measured at the temperature of 160° C. for a sample consisting of LiH ball-milled with carbon (with molar ratio of 1:1).
